Article copy

A gabion retaining wall is a system, not merely a stack of wire boxes. The basket schedule must match the engineered wall geometry, foundation and drainage design, stone fill and installation sequence. Procurement errors often begin when a buyer sends only total wall length and height without a basket-by-basket schedule.

MaiFa lists woven and welded gabion boxes, galvanized and PVC-coated product directions, and several civil or earth-wall applications. Those pages support the product scope. They do not replace a site-specific retaining-wall design or establish load capacity for an unreviewed layout.

Engineering boundary: use this article to prepare the basket RFQ and inspection scope. Wall stability, drainage, filtration, foundation, global stability and local compliance must be determined by the responsible qualified professionals.

1. What MaiFa currently publishes

MaiFa's current product navigation separates woven and welded gabion construction. Product titles show multiple sizes and coating directions, so the purchase file should select one construction and a complete schedule.

Specification area	Published evidence	RFQ action
Basket type	Woven and welded families	Match the engineer's details and identify one type per line item.
Dimension examples	2 x 1 x 1 m, 3 x 1 x 1 m and other custom directions appear	Issue a full basket schedule in millimetres.
Coating directions	Galvanized and PVC-coated products are listed	Define exposure-specific coating requirements.
Fabrication	Cutting, bending and welding services appear	Provide shop drawings and approval workflow.
Intended uses	Earth wall, riverbank and civil references	Require project design rather than relying on catalogue wording.

2. Convert the wall drawing into a basket schedule

List every basket size, course, location and quantity. Identify corner, end, stepped, half-height or nonstandard units. Show diaphragms and connections between adjacent units and courses. A single total volume does not tell the factory which panels and connectors to produce.

3. Define mesh, wire and edge reinforcement

The specification should identify mesh type and opening, wire diameter and tolerance, edge or selvedge wire where applicable, diaphragm construction and lacing or spiral wire. If coated wire is used, define whether dimensions refer to the core or finished wire. Ask the supplier to list deviations from the engineer's schedule.

4. Coordinate coating with exposure

Exposure may include soil, fresh or saline water, wet-dry cycles, abrasion and ultraviolet light. The project specification should select the metallic coating and any polymer overcoat, identify colour where relevant, and define evidence and acceptance methods. Avoid publishing a generic service-life promise because performance depends on environment, damage and maintenance.

5. Plan drainage, filtration and stone interface

Gabions are permeable, but the retained soil and foundation may still require filter layers, geotextiles, drainage details and erosion protection. Stone size should be coordinated with the mesh opening and visible-face requirements. Specify placement lifts, hand packing of exposed faces and limits on deformation during filling.

6. Control course connections and construction sequence

The installation method should show how empty units are aligned, connected and braced before filling; how adjacent units and courses are tied; and when lids are closed. Connector quantity estimates should include corners, diaphragms, lids, course ties and an agreed spare allowance.

7. Separate product supply from site scope

Clarify whether the supplier provides baskets only, baskets plus connection hardware, installation guidance, or any shop-drawing support. Stone, excavation, foundation preparation, drainage, geotextile, plant and local installation are separate unless explicitly included.

Buyer control checklist

A useful procurement file separates the supplier's published range from the exact configuration being ordered. The following controls should be completed before price comparison or purchase-order release.

Attach the engineer's basket schedule and wall sections to the RFQ.
Identify nonstandard corner, end, stepped and transition baskets.
Define wire, mesh, coating, diaphragms and connections by line item.
Coordinate stone grading, filtration and drainage with the design documents.
List supplier scope and site scope separately.
Require drawing approval before bulk fabrication.

Pre-shipment inspection points

Inspection should follow the approved drawing, purchase order and agreed sampling plan. A visual check alone cannot confirm every material or coating requirement, and product inspection does not replace project-specific engineering or local approval.

Reconcile bundle labels and quantities with the wall basket schedule.
Measure representative panels, mesh and wire for each line item.
Inspect joints/weave, edges, diaphragms and coating condition.
Count connection materials and agreed spares by basket type.
Assemble a representative standard and nonstandard unit where practical.

What to include in the quotation

Quotation section	Required information
Design documents	Wall sections, basket schedule, foundation/drainage references and drawing revision.
Basket construction	Welded/woven type, mesh, wire, edge details, diaphragms, lids and tolerances.
Finish	Metallic/polymer coating system, colour, evidence, inspection and repair.
Connections	Lacing, spirals, clips, tie wire, bracing/stiffeners and spare quantities.
Packing	Bundles by wall location or SKU, labels, weights, dimensions and container sequence.
Commercial	Supply exclusions, price unit, Incoterm/named place, schedule, payment and warranty wording.

How to compare supplier offers on one basis

Build a bid-comparison sheet before reviewing price. Give every offer the same rows for product geometry, materials, coating or finish, posts and connections, gates or accessories, drawings, samples, inspection, packing, quantity per commercial unit, package weights and delivery terms. Mark each response as included, excluded, optional or not stated. Where a supplier proposes an alternative, record the changed value and its effect on interfaces instead of treating it as equivalent automatically.

Commercial comparison should use the same Incoterm and named place, currency, quantity, package scope and document requirement. Separate factory price from freight, local tax, installation and project engineering. This method does not select the lowest quotation by default; it exposes omissions and gives the buyer a clear list of technical questions before sample approval or purchase-order release.

Copy-ready inquiry template

Please quote gabion retaining wall baskets to attached drawing [revision]. Basket schedule: [attach]. Construction: [welded/woven]; mesh [ ]; wire [ ]; coating [ ]; diaphragms [ ]; lids and connectors [ ]. Separate standard and nonstandard units, identify all deviations, and include shop drawings, QA plan, package labels tied to wall locations, weights, loading sequence and [Incoterm] delivery to [named place]. Stone, earthworks, drainage and installation are [included/excluded].

Frequently asked questions

Can MaiFa design the retaining wall from a basket quantity?

A basket supplier quotation should not be treated as the full retaining-wall design. Provide engineering drawings and clarify the requested design-support scope.

Why is a basket schedule necessary?

It converts the wall geometry into countable, manufacturable units and prevents missing corner, end or stepped pieces.

Should mesh opening be selected before stone?

Mesh and stone grading should be coordinated together so fill is retained and placed as intended.

Are gabion walls automatically self-draining?

The baskets are permeable, but filter, foundation and drainage requirements remain project-specific.

What should package labels show?

At minimum: SKU or wall location, basket size/type, quantity, drawing revision and accessory package reference.

Request a configuration-specific MaiFa quotation

Send MaiFa the application, dimensions, material and finish requirements, quantities, destination and document scope. Ask the quotation to repeat every selected value and identify any exception. This creates a traceable basis for samples, production, inspection, packing and later repeat orders.
